This must accept string values from the command line, as well as values that are already the correct type. It may also convert other compatible types.

The param and ctx arguments may be None in certain situations, such as when converting prompt input.

If the value cannot be converted, call fail() with a descriptive message.

Parameters:

value – The value to convert.
param – The parameter that is using this type to convert its value. May be None.
ctx – The current context that arrived at this value. May be None.
